Abstract

The transformer (15) has a magnetic core and primary and secondary coils contained within or are in contact with its casing (11). Within the casing, there is moulded resin (14) and pumped dielectric gas in the spaces between the coils. A disc (10) is held directly between the casing and its cover (12) which fixes on cover and forms a channel between the disc and the exterior of the casing. The cover is screwed onto the casing and a ring seal (13) is placed between the disc and the cover. The cover has a series of openings (19) to allow the gas to escape should the disc break. The casing may cover the whole of the core and the primary and secondary coils. Alternatively, it may be a single piece covering the part of the transformer necessary to form the channel between the core and coils and the disc.
